R figure reference

plotly charts are described declaritively in the call signature of plotly::plot_ly, plotly::add_trace, and plotly::layout. Every aspect of a plotly chart (the colors, the grid-lines, the data, and so on) has a corresponding key in these call signatures. This page contains an extensive list of these attributes.

Plotly's graph description places attributes into two categories: traces (which describe a single series of data in a graph) and layout attributes that apply to the rest of the chart, like the title, xaxis, or annotations).

Here is a simple example of a plotly chart inlined with links to each attribute's reference section.

scatter

A scatter trace is initialized with plot_ly or add_trace:

plot_ly(df, type="scatter"[, ...])

                      add_trace(p, type="scatter"[, ...])

A scatter trace accepts any of the keys listed below.

The data visualized as scatter point or lines is set in `x` and `y` Text (appearing either on the chart or on hover only) is via `text`. Bubble charts are achieved by setting `marker.size` and/or `marker.color` to a numerical arrays.

type ("scatter")
x (dataframe column, list, vector)
Sets the x coordinates.
x0 (any)
default: 0
Alternate to `x`. Builds a linear space of x coordinates. Use with `dx` where `x0` is the starting coordinate and `dx` the step.
dx (number)
default: 1
Sets the x coordinate step. See `x0` for more info.
y (dataframe column, list, vector)
Sets the y coordinates.
y0 (any)
default: 0
Alternate to `y`. Builds a linear space of y coordinates. Use with `dy` where `y0` is the starting coordinate and `dy` the step.
dy (number)
default: 1
Sets the y coordinate step. See `y0` for more info.
text (string)
default: ""
Sets text elements associated with each (x,y) pair. If a single string, the same string appears over all the data points. If an array of string, the items are mapped in order to the this trace's (x,y) coordinates.
mode (flaglist)
flags: "lines" | "markers" | "text"
extras: "none"
examples: "lines", "markers", "lines+markers", "lines+markers+text", "none"

heatmap

A heatmap trace is initialized with plot_ly or add_trace:

plot_ly(df, type="heatmap"[, ...])

                      add_trace(p, type="heatmap"[, ...])

A heatmap trace accepts any of the keys listed below.

The data that describes the heatmap value-to-color mapping is set in `z`. Data in `z` can either be a 2D list of values (ragged or not) or a 1D array of values. In the case where `z` is a 2D list, say that `z` has N rows and M columns. Then, by default, the resulting heatmap will have N partitions along the y axis and M partitions along the x axis. In other words, the i-th row/ j-th column cell in `z` is mapped to the i-th partition of the y axis (starting from the bottom of the plot) and the j-th partition of the x-axis (starting from the left of the plot). This behavior can be flipped by using `transpose`. Moreover, `x` (`y`) can be provided with M or M+1 (N or N+1) elements If M (N), then the coordinates correspond to the center of the heatmap cells and the cells have equal width. If M+1 (N+1), then the coordinates correspond to the edges of the heatmap cells. In the case where `z` is a 1D list, the x and y coordinates must be provided in `x` and `y` respectively to form data triplets.

contour

A contour trace is initialized with plot_ly or add_trace:

plot_ly(df, type="contour"[, ...])

                      add_trace(p, type="contour"[, ...])

A contour trace accepts any of the keys listed below.

The data from which contour lines are computed is set in `z`. Data in `z` must be a 2D list of numbers. Say that `z` has N rows and M columns, then by default, these N rows correspond to N y coordinates (set in `y` or auto-generated) and the M columns correspond to M x coordinates (set in `x` or auto-generated). By setting `transpose` to "true", the above behavior is flipped.

- path (string)
  default: "For `type` "path" - a valid SVG path but with the pixel values replaced by data values. There are a few restrictions / quirks only absolute instructions, not relative. So the allowed segments are: M, L, H, V, Q, C, T, S, and Z arcs (A) are not allowed because radius rx and ry are relative. In the future we could consider supporting relative commands, but we would have to decide on how to handle date and log axes. Note that even as is, Q and C Bezier paths that are smooth on linear axes may not be smooth on log, and vice versa. no chained "polybezier" commands - specify the segment type for each one. On category axes, values are numbers scaled to the serial numbers of categories because using the categories themselves there would be no way to describe fractional positions On data axes: because space and T are both normal components of path strings, we can't use either to separate date from time parts. Therefore we'll use underscore for this purpose: 2015-02-21_13:45:56.789"

scatter

A scatter trace is initialized with plot_ly or add_trace:

plot_ly(df, type="scatter"[, ...])

                      add_trace(p, type="scatter"[, ...])

type ("scatter")
x (dataframe column, list, vector)
Sets the x coordinates.
x0 (any)
default: 0
Alternate to `x`. Builds a linear space of x coordinates. Use with `dx` where `x0` is the starting coordinate and `dx` the step.
dx (number)
default: 1
Sets the x coordinate step. See `x0` for more info.
y (dataframe column, list, vector)
Sets the y coordinates.
y0 (any)
default: 0
Alternate to `y`. Builds a linear space of y coordinates. Use with `dy` where `y0` is the starting coordinate and `dy` the step.
dy (number)
default: 1
Sets the y coordinate step. See `y0` for more info.
text (string)
default: ""
Sets text elements associated with each (x,y) pair. If a single string, the same string appears over all the data points. If an array of string, the items are mapped in order to the this trace's (x,y) coordinates.
mode (flaglist)
flags: "lines" | "markers" | "text"
extras: "none"
examples: "lines", "markers", "lines+markers", "lines+markers+text", "none"
Determines the drawing mode for this scatter trace. If the provided `mode` includes "text" then the `text` elements appear at the coordinates. Otherwise, the `text` elements appear on hover.
line (named list)
- color (color)
  Sets the line color.
- width (number greater than or equal to 0)
  default: 2
  Sets the line width (in px).
- shape (enumerated: "linear" | "spline" | "hv" | "vh" | "hvh" | "vhv")
  default: "linear"
  Determines the line shape. With "spline" the lines are drawn using spline interpolation. The other available values correspond to step-wise line shapes.
- smoothing (number between or equal to 0 and 1.3)
  default: 1
  Has only an effect if `shape` is set to "spline" Sets the amount of smoothing. "0" corresponds to no smoothing (equivalent to a "linear" shape).
- dash (string)
  default: "solid"
  Sets the style of the lines.
connectgaps (boolean)
Determines whether or not gaps (i.e. {nan} or missing values) in the provided data arrays are connected.
fill (enumerated: "none" | "tozeroy" | "tozerox" | "tonexty" | "tonextx")
default: "none"
Sets the area to fill with a solid color. Use with `fillcolor`.
fillcolor (color)

- y0 (any)
  Sets the shape's starting y position. See `type` for more info.
- y1 (any)
  Sets the shape's end y position. See `type` for more info.
- path (string)
  default: "For `type` "path" - a valid SVG path but with the pixel values replaced by data values. There are a few restrictions / quirks only absolute instructions, not relative. So the allowed segments are: M, L, H, V, Q, C, T, S, and Z arcs (A) are not allowed because radius rx and ry are relative. In the future we could consider supporting relative commands, but we would have to decide on how to handle date and log axes. Note that even as is, Q and C Bezier paths that are smooth on linear axes may not be smooth on log, and vice versa. no chained "polybezier" commands - specify the segment type for each one. On category axes, values are numbers scaled to the serial numbers of categories because using the categories themselves there would be no way to describe fractional positions On data axes: because space and T are both normal components of path strings, we can't use either to separate date from time parts. Therefore we'll use underscore for this purpose: 2015-02-21_13:45:56.789"
